I still don't understand how RIM ended up deciding on Flash for the Playbook SDK. Flash has never been known for its performance. They might have been able to get away with it on overpowered desktop machines, but performance is critical on a CPU/memory/battery limited mobile device.
Even on with Objective-C on iOS there are a bunch of tricks you have to employ to keep things running smoothly, and if you're not careful you can still end up writing fairly poorly performing apps. I can only imagine this being much, much more difficult if you're working with Flash.
